| Abstract | The occurrence and estrogenic risks of endocrine disrupting chemicals (EDCs) in the Nan River, Phitsanulok wereinvestigated for the first time. EDCs (octylphenol;OP, nonylphenol;NP, bisphenol A;BPA, and estrone;E1) as well as estrogenicactivities (EEQs) were determined using gas chromatography-mass spectrometry (GC-MS) and Yeast Estrogen Screen (YES)bioassay. Concentrations of OP, NP, BPA, and E1in water, sediment, and fish were found up to 36.7, 1060, 1420, and 17.2 ng/L,2.8, 97.3, 13.2, and 12.4 ng/g, and 812, 663000, 339, and 11700 ng/g, respectively. Wet season, EEQs in water, sediment, and fishwere found with means of 0.36 ng/L, 0.1 ng/g, and 0.48 ng/g, respectively; while for dry season those were found with means of0.79 ng/L, 0.87 ng/g, and 0.35 ng/g, respectively. Results of this study showed that the Nan River was contaminated with EDCsand can be harmful to aquatic organisms with high estrogenic risk. |
